This article consists of two parts. The first part summarizes using informal language Wolniewicz’s understanding of the idea of God which he expressed in the language of formal logic. It demonstrates that Wolniewicz’s position was founded on antinaturalism, i.e. the conviction that nature is a fragment of a larger reality while man partly transcends the natural reality. The second part of the article is an attempt at capturing the intuitions behind Wolniewicz’s idea of God as an impersonal power which is not identical with Providence though. It is argued that this view is a consequence of the characteristic traits of Wolniewicz’s personality. This explanation is consistent with Wolniewicz’s understanding of human nature. In the analysis that ensues reference is made to Wolniewicz’s private correspondence.
